Which induction agent is safer for Cesarean deliveries?

• A. Propofol
• B. Ketamine
• C. Thiopental
• D. Etomidate

Answer: (A)

The key idea is choosing an induction agent that provides reliable, rapid unconsciousness for the mother while minimizing neonatal exposure and maintaining stability of both mother and fetus. Propofol fits best here because it induces anesthesia quickly and has a very short duration due to rapid redistribution and metabolism. This means the mother goes to sleep promptly and wakes up quickly after delivery, reducing the time the fetus is exposed to anesthetic levels. Although propofol can cause maternal hypotension, this is manageable with appropriate fluid preload and vasopressor support, keeping uteroplacental blood flow adequate. Compared with the other options, propofol tends to produce less prolonged fetal depression than thiopental, and it avoids some drawbacks of etomidate (adrenal suppression) and ketamine (which can raise fetal heart rate and have other neonatal effects). The combination of rapid onset, rapid recovery, and predictable course makes propofol the safer and more practical choice for cesarean delivery.
